Joseph Grim, a brilliant scientist, achieves the unthinkable: creating an artifact capable of breaking the laws of time and space. A cube, a single button… and a leap into the unknown. When danger forces him to activate it, his life fractures into infinite realities. Each dimension becomes a distorted reflection of his world—an echo of what was and what might have been. But the more he travels, the more his mind begins to fragment, and returning home turns into an obsession.

In one of those dimensions he meets Maryse Blunt, another scientist lost among the folds of time. Together they will try to find their way back to their origin before their memories and their sanity fade completely. Yet the divergence number continues to fall, and each jump brings them closer to a point where everything could begin… or come to an end.

Sin Tiempo is an introspective journey through impossible worlds, where science meets human emotion and eternity is measured in decisions.
